LIGHTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 531,597, dated December1 894. Application filed February 26, 1894. ficrial llo. 501,512. (Nomodel.)

T0 at whom it may concern.-

Be it known that I, BRADFORD H. PENDLE- TON, a citizen of the UnitedStates, residing at specification.

My invention-relates to lighting devices, and my object is to provide ameans for this purpose which is more particularly intended for gaslighting but by slight modification may be readily adapted to use forlighting ordinary oil lamps, gas fires, tire.

The construction, method of applying to an ordinary gas burner, and themethod of operation are described hereinafter, and fully illustrated inthe accompanying drawings, in which- Figure l-is aafront' elevation,attached to a gas burner. Fig. 2 is a left hand side elevation of theconstruction shown in Fig.1. Fig. 3 is \a front and Fig. 4 a sideelevation of the main portion of the case for containing the interioroperative parts, together with the scratcher, as will be furtherexplained. Fig. 5 isa plan view of the construction shown in Fig. 4.Fig. 6 is a front elevation of the front portion of thecase. Fig. 7 is'aview of the opposite side of Fig. 6, showing inside arrangement ofigniting tape and other operative parts. Fig. 8 shows, respectively,front, side and inside elevations of the re -movable front of the case,same as Figs. 6 and 7 but with all the operative parts, except the taperoller, removed. Fig. 9 is a front elevation of the four toothratchetwheel, and Fig. 10 the pawl therefor. Fig. 11 shows,respectively, front and side elevations and a plan View of the weightedoperative lever whose pawl Fig. 10 engages ratchet wheel Fig. 9. Fig. 12is a side elevation of the shaft upon which the igniting tape is woundwhen the device is in action. Fig. 13 is a face and edge elevation ofthe igniting tape, showing arrangement of igniting points.

Similar letters indicate like parts throughout the several views.

The main portion of the case A is rectangular in form and open at bothends and in front, with the exception of two projections B and B nearthe top end. The scratcher C is attached as shown, and its top portionis bent over and down, the point thereof coming in close'proximity to aroller D which is mounted on apin near the top, inside face of the frontpart E of the case, when the parts are all assembled, as in Figs. 1 and2.

At F is the winding shaft which passes through the front plate E of thecase, and is held in position by an inside washer and the ratchet wheelG, both of these parts being firmly secured to the shaft, which is freeto revolve one fourth of a revolution at a time, by pulling downward oncord H whose upper end is attached to the outer end of pawl I which ispivoted to lever J and engages the teeth of ratchet wheel G, lever Jbeing loosely mounted on shaft F between ratchet wheel G and a washer atthe outer end of the shaft; there being an outward projection K of thelower end of the case plate E, to serve as a stop against pulling leverJ around any farther in one direction than is shown by the broken linesFig. 1; and there is another step L to prevent the weight J fromcarrying the lever farther around than the position shown in the solidlines.

There is a spring pawl M, Figs. 1 and 6, having the free end turnedoutward to engage with the teeth of ratchet wheel G, and serves as astop to prevent a backward movement thereof.

The pawl I is strongly pivoted to the end of lever J, by a portion ofthe end of the lever being bent upon itself to form a lug so that thepawl pin is supported at both sides of the pawl, and may therefore becomparatively small. The pawl operates without the aid of a springthrough the weight of the attached cord and its knob, there being aprojection at I of the pawl which serves to pre vent it moving far fromoperative position baokwardly.

.The tape N for holding the igniting points 0, is first placed in thecoiled form around a pin P, after which its outer end is brought uparound the roller D, thence down to the winding shaft F, where the endis inserted in the slot R and the shaft given a revolution to fasten theend of the tape therein. It is obvious that, since shaft F is turnedbuta fourth of a revolution at each pull of the cord H, this actionwould cause a less length of tape to bewound on shaft F at each fourthof a revolution at the beginning than when the tape has been almost allwound upon the shaft, so that, the igniting points 0 are placedgradually wider apart from the first to be used of the series, to thelast, as is shown in Fig. 13, this arrangement of the igniting pointsinsuring that but one at a time will be ignited by each pull of thecord.

The inside end of shaft F is prolonged sufficiently to enter a hole Q inthe rear through the main portion of the case, when the portion shown inFigs. 6 and 7 is slid up into the main case under the projections B andB, the projections pressing upon the front plate E which serves as aspring to first bend outward and finally to force the end of the shaftinto the hole Q, and thus form a catch to hold the two parts of the casein proper relative position. The front plate E, together with theoperative parts are easily removed by first lifting outwardly upon thelower end of the plate, which disengages the end of the shaft, afterwhich the plate may he slid downwardly and out.

It will be understood that the stud pin upon which roller D is mountedto revolve is of a length sufficient to cause its free end to pressagainst the inside of the back of the casing and hold the front plate Eclose against the projections, B, B. By successively pulling downwardlyupon cord I-I all of the igniting points 0 maybe fired as they passunder the scratcher C, as usual. The operative parts being all attachedto the front plate or lid of the case, which has no projecting sides,the tape may be easily removed and a new tape put in its place.

I claim as my invention 1. In a lighting device, the case thereforcomprising a back portion with sides and inward projections B and Btherefrom, as described, the front side comprising a plate having theoperative parts attached thereto, which plate is adapted to slidelongitudinally into the said back portion under the said projections, ahole Q in the back portion to receive the free end of shaft F and servein combination with the said projections for the purpose stated.

2. The combination in a lighting device having the main portion A of thecasing with sides and projections 13 and B therefrom, and a scratcher Cattached thereto, as described, of the front plate of the case with aroller mounted to revolve at one end thereof, and a tape winder shaft atthe other, a tape having a series of igniting points thereon coiledaround a pin between the roller and the shaft, a portion of the tapepassing over the roller under the scratcher, and one end attached to thewinder shaft which is adapted to wind up the tape and successively firethe igniting points, as shown and described.

3. In a lighting device, means for operating the tape winding shaft,comprising a ratchet wheel secured thereto and a weighted lever looselymounted thereon, a pawl pivoted to the lever and adapted to engage theratchet wheel, an actuating cord attached to the pawl and stops on thecase for limiting the motion of the lever, and a pawl for preventing abackward motion of the ratchet wheel, the parts operating in combinationfor the purpose stated.

4. In a lighting device of the class described having a tape windershaft with a limited intermittent movement, the tape having ignitingpoints disposed thereon at a gradually increasing distance apartfronfthe first used to the last, for the purpose stated.

In testimony that I claim the foregoing I have hereunto set my hand,this 15th day of February, 1894, in the presence of two witnesses.
